Structuring and articulation of Rorschach inkblots in relation to alcohol consumption: a co-twin control study

20 male, alcohol-discordant twin pairs, aged 45 to 65 yr. were compared for ability to structure and articulate Rorschach inkblots. The Rorschach responses were evaluated by a new rating scale technique. Data were analyzed by means of one-sample t and multivariate Td2 tests. No relationship between alcohol consumption and tendency to articulate and structure could be established.
